SPECIFICATION forming part of Lettersratent'No. 687,061,1:1atea1v0vember19, 1901. lApplimtion filed February 11,1901. Serial No. 46,800. (Nomodel.)

BROWN, citizens ofthe United States, and resi j dents of Coldwater, inthe'county of Branch and State of Michigan,- have invented a new andImproved Drier, of which the following is a full, clear, andexactdescription.

This invention relates to improvements in driers for slurry cement,clay, or other material designed to be calcined in a kiln; and theobject is to provide a drier of simple conf struction and arranged touse the excess or escape heat of a kiln as a drying medium.

We will describe a drier embodying our invention and then point out thenovel featuresA in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, l

in which similar characters of reference indicate corresponding parts inall the figures.

Figure 1 is a partial section and partial elevation of a drier embodyingour invention.

Fig. 2 is a partial section and and partial ele-` vation at rightanglesto Fig. 1. Fig. 3 is a top plan view. Fig. 4 is a section on the line 44 of Fig. 1. Fig. 5 isa detail showinga scrapercarrying arm employed,and Fig. 6 is a section on the line 6 6 of Fig. 5.

The drier comprises a cylinder 10, at opposite sides of which areextensions or lues 11, and the device is placed upon the outlet orchimney 12 of a kiln and communicates there` with through pipes 13.Arranged within the cylinder are a number of drying-platforms 14, leachprovided with an opening 15, through which material may discharge fromone platform to another. These platforms extend alternately fromopposite sides of the cylinder and have openings alternately vatopposite sides for the passage of heat, as clearly indi- Extended upwardthrough the several platforms is a shaft 16, on the lower end of whichis a gear-wheel 17, designed to be engaged by any suitable device toimpart a rotary movement to the shaft. The shaft 16 at its lower end hasconnection with a collar 18, which is mounted to rotate on a block 19,and ball or roller bearings are lplaced between said collar and block.The

.upper end of the shaft has a bearing in a boxing 20,l attached to rodsextendingA across the llchimney oroutlet 2l vof the cylinder.

Mounted on the shaft above each platform 14 is a scraper-carrying arm22. These sev- 'eral arms are variously arranged as to their joutwardprojection, from the shaft, and it may l be here stated that theopenings 15in the several platforms are arranged out of 'line oneiwithianother. Mounted on the arms 22 are scraper-blades 2:3. Thesescraper-blades are ,curved in the direction of their movement, 'and' ashere shown they are removably connected toblocks 24adjustablelongitudinally on the arms andare held as adjusted by setserews Y25.While we have shown scrapers as applied to the lower arm in Fig. 2, itis to be lunderstood that they are designed to be connected to all ofthe arms and as many scrapers as desired may be placed upon each arm.

In operation the material to be dried is fed through the pipe 26,leading through the top of the cylinder, and falls upon the uppermost.platform 14. The Scrapers rotating over this uppermost platform willkeep the material in motion, and as the material reaches the opening l5in said uppermost platform it will pass downward upon the next of theseries, and this will be continued until it reaches the lowermostplatform, from which it passes through a chute 2'7 into the kiln. Duringthis operation the heat will pass upward through one flue 11 vover theplatform, thence through the opposite i'lue 11 over the next platform,and thus continueuntil it finally escapes through the chimney 2l. l

For the purpose of adjusting the parts or for cleaning the platformswhen necessary the cylinder is provided with door closed openingsbetween the platforms.' @It will be noted that the arms 22 are adjustably connected to the shaft 16 and may be held as adjusted verticallythereon by means of setscrews.

A device embodying our invention may be economically operated, becauseit uses waste gases or heat from the kiln, and as the material will bein comparatively thin layers it IOO Having thus described our invention,we claim as new and desire to secure by Letters Patent- 1. A drieradapted for connection with the heat-escape iiue of a kiln, andcomprising a cylinder having vertically-arranged extensions formingfiues at opposite sides, a series of platforms arranged in the cylinderand extending alternately from opposite sides thereof at the extensions,and terminating alternately at opposite sides at the ilues formingopenings for the passage of heat, each of said platforms having anopening for the discharge of material, a shaft extended upward throughthe partitions, an arm on the shaft above each platform, andscraper-blades carried by the arms, substantially as specified.

2. In a drier, a platform having an outlet, a shaft extended through theplatform, an arm adjustable at one end on the shaft and having aT-shaped portion, a block adjustable longitudinally on the T-shapedportion of the arm, and a curved scraper removably connected to theblock, substantiallyas specified.

3. A drier adapted for connection with the heat-escape outlet or chimneyof a kiln, and comprisinga cylinder having an outlet at its top andpipes at its lower end arranged t-o communicate with the said outlet ofthe kiln, the said cylinder being provided with vertically-arrangedoffsets or extensions at opposite sides forming iues, a series ofplatforms arranged in the cylinder and extending alternately from thewalls of the fines at opposite sides and terminating alternately at thesaid fines forming openings for the passage of heat, the said platformsbeing each provided with an opening for the discharge of material, a'`
